What this research studies

You or your child would breathe into a small device that samples exhaled air to capture chemicals (volatile organic compounds) linked to worsening lung symptoms. The team will use machine learning on breath data to find a biosignature of pulmonary exacerbations. Engineers will build a nanosensor array that can detect that biosignature in real time and connect it to a user-friendly smartphone app for home or clinic use. The work aims to create a rapid, noninvasive tool to warn families and clinicians of impending flare-ups so treatment can be started earlier.

Who could benefit from this research

Good fit: Children with cystic fibrosis (approximately 0–11 years old) whose caregivers can provide consent and who can use a breath collection device are the ideal candidates.

Not a fit: Adults with cystic fibrosis, people without CF, or children who cannot provide breath samples (due to age, severe illness, or device limitations) may not benefit from participating.

Why it matters

Potential benefit: If successful, this could help catch CF lung flare-ups earlier, reduce unnecessary antibiotic use and hospital visits, and limit loss of lung function.

How similar studies have performed: Prior small studies of breath VOCs and prototype sensors have shown promise, but real-time handheld detection of pediatric CF exacerbations using AI remains largely novel.
